Abstract

The main authorities and practitioners face crucial challenges in safeguarding wildlife and conservation areas due to massive direct anthropogenic disturbances, such as illegal logging, habitat conversion into human development areas, and wildlife poaching. Therefore, measuring the effectiveness of wildlife and habitat protection is essential for wider conservation intervention. This study aimed to examine patrol effectiveness using measurable effort and parameters of SMART-based data collection in Rimbang Baling and Bukit Betabuh, Sumatra. We conducted a series of planned SMART-based data collections in designated patrol blocks of Rimbang Baling from 2014 to 2018. We implemented catch per unit effort (CPUE) measurement by the number of detected illegal activities and then a generalized linear model (GLM) to assess the relationship between patrol efforts and threat numbers. This study covered 209 patrols within 2,129 patrol days, 13,153.05 patrol hours, and 14,864 km. The CPUE value decreased from 0.381 to 0.191. Our GLM showed that patrol efforts significantly reduced threat numbers. This study provides new knowledge regarding SMART-based data collection and its ability to increase the effectiveness of patrols in promoting better protection and threat reduction in conservation areas in Indonesia.

Abstract

Malay apple (Syzygium malaccense L.) is a tropical fruit species grown in the fruit garden section of Liwa Botanical Garden, West Lampung, Indonesia. Insect communities play an important role in agroecosystems because they consist of both pest species and beneficial organisms such as predators and parasitoids. This study aimed to determine insect diversity and dominance on Malay apple plantations in the Fruit Garden of the Regional Technical Implementation Unit (UPTD) of Liwa Botanical Garden. The observation was conducted from September to October 2021 using direct observation, pitfall traps, and yellow sticky traps across five sampling plots arranged diagonally. Insect identification was conducted based on morphological characteristics using relevant literature. Species diversity was evaluated using the Shannon–Wiener diversity index (H’), while dominance was measured using Simpson’s dominance index (C). A total of 1,594 insect individuals belonging to nine orders were recorded, including Diptera, Hymenoptera, Orthoptera, Hemiptera, Coleoptera, Lepidoptera, Dermaptera, Odonata, and Neuroptera. The diversity index (H’) was 1.44, indicating moderate diversity, while the dominance index (C) was 0.43, suggesting low dominance. Diptera was the most abundant order, dominated by fruit flies (Bactrocera dorsalis and Bactrocera cucurbitae). The results indicate that the insect community structure in the Malay apple plantation is relatively balanced, although fruit flies have the potential to become major pests. Increasing plant diversity through flowering plants (refugia) is recommended to support beneficial insect populations and maintain ecosystem stability.
